Abstract : –EMCElectromagnetic Compatibility studies require the modeling of the printed circuit board PCB. Such models need to be compatible with the simulation software usually used in the industry. An analysis for modeling and optimizing the PCB is presented in this study. The method of moments is used to determine a transmission line electrical model RLGC for traces. This model is based on the physical geometry of traces and the material characteristics of the copper and the dielectric. Given the PCB model, an optimization can be performed to minimize the conduction emissions of the board.
